ltailway-Frogs, of which the 'ollowing is a specification.

.\l invention relates to railway t'rogs cast. or nnule in one piece, andhas for its ohject such :rtlesign and arrangement of the parts as willprovide a fixed and positive connection ht-tween the rails and frogproper remove the-shock occasioned hy the wheels when passing over thejoints where the rails join the 'lrog, p event the flanges of the wheelsfrom cutting, hitting, or riding the point of the frog; also to providea proper means for electrically connecting or honding the frog into thegeneral track 'systetn, all of which is more fully descrihed andclaimed.

By reference to the drawings forming a part of this specification,Figure 1 is a top view or planet my improved frog, Fig. 2 is a sectionof the same on the line lI-TI in Fig. 1. Figs. 3,4. and .3, areseetionsoirthe tines llllll, 1V-1V, and V-V, respectively in Fig. 2,looking in the direction of the arrow, Fig. 6 is an end view of one halfof the frog looking in the'same direction,

and it'will he noted that in addition to the point 1, and heels 2, thereare the fish plates El, 3, 3. made int gral with the frog proper; thesefish plate are further reinforced hy the flanges l, 4, and verticalprojections .7, .7, which project alongthe side of the top flange of therail. high enough to 'otl'er a support to thd wheels passing over therail. n such a manneuthat at the time the wheels pass. the joints 6; 3,they will be entirely supported thereon and prevented from pounding asthey would otherwise.

Inasmuch asthetread of the wheels rapidly heroine grooved. due to theconstant friction upon the rail, thus forming a projection or flange onthe outer side of the mint 1 or take the course on'the wrong side ever.thistendency is overcome as tnat part of the tread which hes beyond therail and forms the secondary flange ahove alluded to,

rail from the, flange proper. there Is always a tendcncygor of thepoint. In my i'in n'oved fr g. how

rides up over the heel on the'vertical pro-- jeetion 5, thus causing thewheel to trail naturally along its proper path. The projections 5, mayhe cut away, forming inclined surfaces 12-12, so that. this transferenceof weight from rail'to lish plate and irog takes placegradually, thuspreventing all shocks that oc ur when two rails or incinhers meet as inthe ordinary way. The sectionot' the fish plates 3, I and the fact thatthey are integral with the "frog, gi\'t-..t-ltein sutiicient strengthand rigidity to inalie the curve thus insuring the proper approach anddeparture to and from the frog. A tlange or base 7 isprovided w ith ahole '8 into which the honding wires can he attached. It referred tohave the web 11 which attac res the point to the heels just. lowenoi'igh to allow the flanges of the wheels to pass "there through, andit may he high enough to act as a support to the wheels through theflanges, in whichcase it is preferahle to have inclined approaches 10',10, thereto; for in this construction the total strength of the frog mayhe made the greatest with the least .wei'ght of material; it alsoprevents dirt from accumulating there, or anyones foot from gettingaccidentally caught therein.

\Vhile I have described with particularity one form of frog, carryingout my invention it will l )e'readily seen some ot 'the advantagesthereof could he ohtai'nerl by making thc'same in two or more pieces, bychanging the form, and in other ways so, I do not conthe tornrsh wn.

I claim as my invention is as follows; 1. A railway track structure haring atone detaclnihly secured, and which fit the said and constitutethe only means of ltee ling the rails in alineinent with the parts oftlletltifik structure with which the railsare supposed to register. t o

railway tltlt'h structure having at one end two arms against which tworails are detachahly secured and; which fit the said rails between theirtopand hottoin flanges and having a projection extendingup along theside of the head of the-rail to the top thereof, the said armsconstituting the only 'means of keeping the rails in alinement with theoartsof the track structure with which the rails are supposed toregister.

rails, when holted thereto, assume the proper Having described rayimprovedlrog what end two arms against which two rails are" fine myselfas regards my hroader claims to rails hctwet-n their top and bottomflanges endtwoarms. against'whi ch two rails are 3. A railway trackstructure having at one det'achably secured and which fit the said railsbetween the top and bottom flanges and have a projection extending upalong the side of the head of the rail to the top thereof, the said.projection being provided with inclined surfaces adapted to graduallyreceive the Weight of the wheels traveling, thereover',

the sa'idarni'si forming the only means of keepingthe rails in alinementwith the parts of the track structurewith which the rails are supposedto register.

' 4. A'railway track structure having at one end two arms one side ofeach being parallel to the path of the Wheels passing thereover andwhich fit the rails between the top .and

bottom flanges on one side of therail only in such a manner that whenthe rail is secured against the arms the operative side of the head ofthe rail shall be in approximate alinement with an operative side of thetrack "structure, the said arms forming the only means "of attaching therails to the track structure, substantially as set forth.

5. A railway track structure having at one end two arms one side of eachbeing parallel toLthe path of the wheels passing thereover v and whichfit the rails between the top and bottom flanges on one side of the railonly in such a manner that when the railis secured a ainst thearms, theoperative sideof the head of" the rail shall be in up roximate' such amanner tha alinement with an operative side of the track structure, thesaid arms being provided with a projection extending up along the sideof the head of the rail. to the top thereof the said arms forming theonly means of attaching the rails to the track structure, substantiallyas set forth.

6. A railway track structure having at one end two arms-one side ofeach'being-parallel to the path of the wheels passing thereover andWhich'fit the rails I bottom flanges on one side of the rail only inbetween the top and ,agalnst the arms, the operative side of the head ofthe rail shall be in approximate ahnement with the operative side of thetrack structure, the said arms being provided with 1 a projectionextending up along the side of the head of the rail to 'the top thereof,top 7 surface being inclined toward tllGSlllllCtltt'G of which it formsa part, sul'istantially'" as set forth. I

7. A railway track structure having at one end two arms which rest onthe top of the bottom flange of the rails and extend up along the sideof the top flange of said rails approximately to the top thereofandhaving their top surfaces inclined toward the body of the structure,substantially as set forth.

' 8. A railway-track structure having'a heel rail wider than the head ofthe rail to which it attaches and provided with an inclined surfaceadapted. to gradually receive the load from that portion of the wheeltread which extends .over the outside of the rail head, substantiallyasset forth.

9. A railway track structure having a heel rail Wider than the rail headto which it attaches and provided with an arm alongthe outside of thesaid rail, the said arm fitting the said rail between the top and bottomflanges and extending up along the side of the head of the rail to thetop thereof, the said arm forming the sole means-of con-- necting theheel rail to the rail with which it coiiperates', substantially as setforth.

10. A. frog heelrail' having atone end an arm which rests on the top ofthe bottom t when the rail is secured P. Gr. ELDER.
